What will happen if I don’t subscribe to a new plan or auto renew my plan when the current month is over? How long will my account be active?

You will have a grace period of 60 days to renew your plan or create a new one. Your account will still be active during this time (i.e. it will still receive incoming calls and SMSes). After 60 days, your account will be terminated and you will no longer be able to use your line.
